    • PROBLEM TO BE SOLVED: To provide a hot water manufacturing supply unit capable of stably manufacturing and supplying hot water at high temperatures from heat of steam by including a configuration capable of preventing cavitation of hot water in a hot water pump inlet.SOLUTION: A hot water manufacturing supply unit 1 includes a heat exchanger 2 heating hot water by indirectly making steam contact hot water, a hot water pump 3, an expansion tank 4, and a hot water temperature control part 9. The expansion tank 4 is connected to a hot water suction side of the hot water pump 3 of a hot water transfer pipe line 14a via a branch pipe line 15, and is arranged and composed to have a potential head (a liquid head) for applying a pressure to the hot water suction side. The hot water temperature control part 9 is configured so as to adjust an opening of a steam flow control valve 23 and to control a flow rate of the steam to be supplied to the heat exchanger 2 such that a detection value of a temperature sensor 28 becomes a predetermined value within a range of, for example, 85-95°C.
    • 要解决的问题:提供一种热水制造供应单元,其能够通过包括能够防止热水泵入口中的热水气化的构造来稳定地制造和供应高温热水的热水。 解决方案:热水制造供应单元1包括:热交换器2,其通过间接制造蒸汽接触热水来加热热水,热水泵3,膨胀箱4和热水温度控制部分9.膨胀 水箱4经由分支管路15连接到热水输送管线14a的热水泵3的热水吸入侧,并且配置成具有用于施加压力的电位头(液体头) 到热水吸力侧。 热水温度控制部9被配置为调节蒸汽流量控制阀23的开度,并且控制供给到热交换器2的蒸汽的流量,使得温度传感器28的检测值变为 在例如85-95℃的范围内的预定值。 版权所有(C)2012,JPO&INPIT
